Color-filter-less liquid crystal display device, display control device and display control method thereof

A display device, comprising:

• a plurality of backlight modules, wherein each backlight module comprises a plurality of light sources capable of emitting light in at least three different colors;
• a color-filter-less liquid crystal display module comprising a plurality of pixel units arranged in an array form and a plurality of scanning lines coupled to the pixel units, wherein the plurality of backlight modules are arranged in parallel with the liquid crystal display module, wherein an orthogonal projection of each backlight module onto a plane where the liquid crystal display module is located corresponds to at least two rows of pixel units, and wherein the pixel units in one row are along an length extension direction of each scanning line;
• and
• a driving circuit coupled to each backlight module and configured to apply a backlight driving signal to each backlight module,
• wherein each backlight module further comprises
• a collimating structure configured to perform collimating calibration on the light emitted by the backlight module, wherein:
• the collimating structure comprises a cup-shaped body disposed surrounding each light source, and an interior surface of the cup-shaped body is a reflective surface;
• and
• the collimating structure further comprises a light shielding baffle plate disposed between two adjacent backlight modules, the light shielding baffle plate being higher than a plurality of pixel units.
